DRAG-SORAPER EQUIPMENT.

Application filed January 17, 1924. Serial No. 686,721.

To all whom it may concern:

Be it known that I, WILLIAM E. HALE,

a citizen of the United States, residilnag at- Fort I/Vashington, in the county of ontgomery and State of Pennsylvania, have invented a new and useful Improvement in Drag-Scraper Equipments, of which the following is a specification.

The principal object of the present invention is to effect an economy in the overhead car dumping structure or span and at the same time to provide a large storage area in the yard.

Other objects of the invention will appear from the following description at the end of which the invention will be claimed.

In the following description reference will be made to the accompanying drawings forming part hereof and in which- Figure 1 is a diagrammatic view illustrating in plan drag scraper mechanism embodying features of the invention.

Fig. 2 is a transverse sectional view taken on the center broken line of Fig. 1, and

Fig. 3 is a similar view illustrating a modification from which the rear wall is omitted.

In the drawings 1 is a railway line. 2 is a short dumping span interposed in the line, and by short dumping span is meant that the girders 3 which span the trestles or abutments 4 are relatively short in comparison with the wide angle 5 that bounds the storage area of the yard in front of the line. 6 is a front block structure arranged to bound the storage yard. It is shown to consist of a series of spaced blocks but the intention is to include a movable block or blocks. 8 is a back block structure arranged at both front and back of the line and contiguous to the dumping span. 9 is a powerhouse arranged in the yard and outside of the storage area. 10 is a drag scraper and the full lines 11 indicate one position of the cable by which it is operated at the extreme boundary of the angle 5. The broken lines 12 indicate another position of the cable when the drag scraper is operated at the other extreme position of the angle 5. The lines 13 indicate another position of the cable when the drag scraper is operated from the back of the line 1. 14, Figs. 1 and 2, diagrammatically represents the pile of material that is dumped from the span, for example, from the car 15. In Fig. 3 16 represents the pile of material.

It will be obvious to those skilled in the art to which the invention relates that modifications may be made.in details of construction and arrangement without departing from the spirit of the invention which is not limited as to such matters or otherwise than as the prior art and the appended claims may require.

I claim:

1. Drag scraper equipment for railway dumping spans and their storage yards comprising a block structure located under the span and arranged at the ends and back portion thereof to provide for taking material from under the span and to command a large storage area.

2. Drag scraper equipment for railway dumping spans and their storage yards comprising a block structure located under the span and disposed at the back and ends of the span and a second block structure arranged to bound the storage area, whereby the length of the span is short in respect to the storage area of the yard.

WILLIAM E. HALE.
